Abstract

The present invention includes producing a first processed signal which localizes sound image at a first localization position and a second processed signal which localizes sound image at a second localization position; multiplying one of the first and the second processed signals by a coefficient k which varies in the range of 0 to 1; multiplying the other signal by a coefficient 1-k; and adding the processed signal multiplied by the coefficient k and the processed signal multiplied by the coefficient 1-k. When the predetermined position is located away at an angle  in a circumferential direction from the front of the listener, the first localization position is in the vicinity of the predetermined position and located away at an angle 1 in a circumferential direction from the front of the listener wherein 1 < , and the second localization position is in the vicinity of the predetermined position and located away at an angle 2 in a circumferential direction from the front of the listener wherein 2 > .
